In order for the mailman to deliver post to your home, they will naturally need your address. The Internet works in exactly the same way. Every time you visit a website or need to download a file the site server will need to know your IP address.
Without an IP address, you wouldn't be able to use the Internet, because the server wouldn't know where to send the files. With a VPN, you can hide your real IP address by tunnelling traffic through a private network back to yours.
VPN is an abbreviation for "Virtual Private Network" and its an encrypted direct connection between your computer and a VPN server. It is called virtual because the user sees a VPN connection as if it is a private connection, although it takes place over the internet.
This makes it possible to be anonymous on the Internet, and can be used to trick services into believe that you are somewhere else in the world than your actual real location. This in turn can be used to increase access to websites which would normally be blocked in your country.
It creates a point-to-point connection over the internet, via a dedicated, encrypted line between two servers. VPN users a private network over the Internet, while maintaining the characteristics of a normal connection. Your computer will appear as if it belonged to the local network of a VPN server.
A VPN server is a anonymous way to use the internet, because no one can track you, or monitor you. Using VPN ensures that your Internet traffic is always encrypted.
